Description: 程序的主要功能是做了一定范围的信噪比下，对每个信噪比：随机信号QPSK调制；
根据Alamouti方案的矩阵进行编码；发送信号经过瑞利信道和加入高斯白噪声；
接收信号采用最大比合并的方法；最后对合并信号进行最大似然判决并求误符号率。
结果表明10^-3对应大约12->13dB-Procedure main function is to do a certain range of SNR for each signal to noise ratio: random signal QPSK modulation program in accordance with Alamouti coding matrix send signals through Rayleigh channel and adding Gaussian white noise received signal using maximal-ratio combining method Finally the combined signal and the maximum likelihood decision for symbol error rate. The results showed that about 10 ^-3 corresponds to 12-> 13dB

Description: 多径信道仿真
有三条固定路径的AWGN多径信道的QPSK系统进行BER性能方针，并与在理想的AWGN信道中同样系统的BER进行比较，为简化模型，作如下假设：
1，信道中有三条路径，包括一条没有衰落的LOS路径和两条具有瑞利衰落的路径。与各路径相应的接收功率以及路径间的延迟差是仿真的参数
2，信道的锐利衰落仅影响发送信号的幅度，不影响瞬时相位。
3，在符号间隔内各多径分量的衰减幅度是常数，并与相邻间隔无关。-Multipath channel simulation There are three fixed path multipath AWGN channel BER performance of QPSK systems approach, and in an ideal AWGN channel BER the same system for comparison, in order to simplify the model, make the following assumptions: 1, There are three channels path, including a no decline LOS path and the two have a Rayleigh fading path. Corresponding with the path to receive power as well as the path delay difference between the simulation parameters of 2, channel sharp decline affects only the magnitude of the transmitted signal, does not affect the instantaneous phase. 3, in the symbol intervals multipath component of the decay rate is constant, and has nothing to do with the next interval.
